Callback

The following table shows the supported IPNC Callback types.

Callback Option	Description
Disable (Default)	Callback is not enabled
LCP	After authentication the incoming call is
Link Control Protocol	dropped and an outgoing call to the
	number configured in the Service will
	be made to re-establish the link.
Callback CP	After acceptance from both ends the
Microsoft's Callback Control Protocol	incoming call is dropped and an
	outgoing call to the number configured
	in the Service will be made to re-
	establish the link.
Extended CBCP	Similar to Callback CP however the
Extended Callback Control Protocol	Microsoft application at the remote end
	will prompt for a telephone number. An
	outgoing call will then be made to that
	number to re-establish the link.

The following points must be noted for Callback functionality

•Callback for an incoming call is configured on a RAS and for an outgoing is configured on the Service.

•For an incoming call the Callback option need NOT be set on the Service. Setting Callback on a Service allows the IPNC to negotiate Callback when initiating the call.

•For all Callback types an intranet service type must be used.

•To support a mixed environment where some incoming calls do not require Callback a separate RAS’es must be configured (with a unique DDI) with and without Callback enabled.

•Certain Callback types maybe configured to circumnavigate Time profile restrictions.
